The Socialist Party of Greece (Greek: Σοσιαλιστικό Κόμμα Ελλάδας, ΣΚΕ) was a political party in Greece. The party was formed in 1920, as an anti-Comintern minority split away at the second congress of the Socialist Labour Party of Greece. The group that founded the Greek Socialist Party was led by A. Sideris. The party was active in trade unions, and in 1931 the leading party member Dimitris Stratis was elected General Secretary of the General Confederation of Greek Workers (G.S.E.E.). The party was a member of the Labour and Socialist International between 1923 and 1931, and again in 1933.
